Repair Instructions

If diagnostics confirm that the fuel pump is failing, follow these repair instructions:

1. Prepare for Fuel Pump Replacement:

Disconnect the negative battery terminal to prevent electrical shorts.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.

2. Access the Fuel Pump:

Depending on the model, the fuel pump can be accessed through the rear seat or by removing the fuel tank.
For rear seat access:
- Remove the rear seat cushion and locate the fuel pump access panel.
- Remove the panel screws and lift the panel to expose the fuel pump assembly.

3. Disconnect Fuel Lines and Electrical Connectors:

Use a fuel line disconnect tool to detach the fuel lines from the pump assembly.
Disconnect the electrical connector from the fuel pump.

4. Remove the Fuel Pump Assembly:

Unscrew the retaining ring or bolts securing the pump assembly to the tank.
Carefully lift the assembly out of the tank. Be cautious of fuel spillage.

5. Install the New Fuel Pump:

Compare the new pump with the old one to ensure compatibility.
Install the new fuel pump into the assembly, securing it as per the manufacturer's specifications.

6. Reinstall Fuel Pump Assembly:

Place the fuel pump assembly back into the tank and secure it with the retaining ring or bolts.
Reconnect the fuel lines and electrical connectors.

7. Reassemble the Vehicle:

If applicable, reinstall the fuel pump access panel and rear seat.
Reconnect the negative battery terminal.

8. Test the System:

Reinstall the fuel pump fuse.
Turn the ignition key to the "ON" position a few times to prime the system.
Start the engine and check for leaks or abnormal noises.

Conclusion

If you've followed these steps and symptoms persist, further diagnostics may be required, or other components such as the fuel filter or injectors may need to be checked. Always refer to the official Toyota service manual for specific details related to your vehicle.
